SGRAPER FOR BELTS.

Specification of Letters Patent.

To all who) itmag concern:

Be it known that I, FRANK A. Goonrn'oox'rz, a citizen of the United States, residing at Miami, in the county of Gila and State of Arizona, have invented new and useful Improvements in Scrapers for Belts, of which the following is a specification.

In endless conveyors employed in handling plastic material, such materials necessarily stick to the belt, and unless such substances are removed the conveyor is rendered defective. A direct scraping of the conveyor belt will wear down the same, thus shortening the life thereof, while any hardened member directly contacting with the belt, even intermittently, will inflict injury to the belt.

It is the primary object of'this invention to provide a means for removing foreign substances trom an endless belt conveyor which will deliver intermittent blowsto the belt and intermittently scrape the belt, the construction and arrangement of the same being such, however, as to inflict no injury to the belt.

In carrying out my invention ll propose to provide a shaft or drum with radial arms havin on the ends thereof strips of yieldable matenal, the shaft or drum being latched to the motive power which produces the conveyera-nd being so arranged as to' deliver light blows to the conveyor, upon the bottom lead thereof as well as to impart scraping action to the said lead, and thereby automatically relieve the belt of substances or particles adhering thereto.

I accomplish the foregoing objects and others which will appear as the nature of the invention is better understood, by a simple construction, combination and arrangement of parts, a satisfactory emloodime tof which is illustrated by the drawings, in which,

Figure l. is an edge view of an endless conveyer illustrating the application of the im provement. 7

Fig. 2 is a greatly enlarged sectional view approximately on the line 2-2 of Fig l.

3 is a perspective view of-the scraper, the flexible belt in contact therewith. being removed.

Fig. 4 is'aperspective view of one of the belt contact" members. i

Fig. 5 is a view of the shaft for ti provement.

Fig. 6 is a detail sectional .view illustrating the manner in which the drums aresecured on the shaft.

Referring-now to the drawings in detail center of the roller 7, is a shaft 11.

. with the under lead of disclosed in Figs. 1' and 2 of the drawings, 5

6 designates an endless conveyer belt and '1 one of the pulleys around which the belt travels. The pulley 7 ma 1 have its shaft 8 connected to the source of power for operating the belt, but for the purpose of this invention it has not been deemed necessary to illustrate the motive power.

While in thedrawings I have illustrated the improvement as deriving power from an idler 9 that is contacted and revolved by the lower lead of the conveyor belt 6, it will, of course, be apparent that the improvement may be hitched directly to the shaft 8, or to the shaft of any of the rollers for the belt 6.

Journaled in suitable bearings provided in uprights 10 arranged to theopposite sides of the conveyer belt 6, and preferably positioned a slight distance inward of the axial This shaft is provided with spaced keyways 12 within which are arranged keys 18 that also pass through keyways 14.- in wheels or drums 15, any desired number of the latter being employed, and the same being preferably spaced away from each other. As disclosed by the drawings the drums 15 are preferably in the nature of flat disks and are each pro vided with a desired number of equally spaced arms 16 which radiate from the drums 15. The arms 16,12 1. the outer ends thereof are bent upon themselves to provide larly disposed flat flanges l7. Secured to the flanges are metal plates 18, and secured to the said plates 18 are the scraper plates 19. The plates 19 are constructed each of a strip of yieldable material, such as rubber, the 'same having their outer edges pro ecting a suitable distance beyond the outer edges the plates 18', and the scraper plates 19 3 preferably adjustably connected to the plates 18. This is accomplished by providing me plates 18 with elongated openings :20 which register with the openings in the plates 19 through which the securing elements pass, but if desired, a plurality of elongated open-- ings enay be arranged on the scraper plates.

The scraper plates are disposed. to contact the belt 6, as clearly so that both a shaking and scraping" action will be impart ed to the lower lead of the belt when the device is operated.

On the shaft 11 is secured around which is trained t-wistc idler 9. It will be apparent that when the 119 the said. belt being also trained around. the I belt is in operation and moves in the direction of the arrows illustrated in F 1 of the drawings the idler 9 will be turned in the direction of the arrow shown on the said figure, revolving the scraper members in an 0ut- ,ward direction, or in a direction opposite to that of the movement of the belt 6,

' The device is extremely slmple, may be easily and cheaply set up in connectlon with any ordinary construction of conveyer belts shaft arranged therebencath and operated thereby, drums on said shaft, radial arms pr01ecting from said drums having fiat flanged ends, plates secured to said ends, and

. the outer incense elastic scraper plates adjustably connected to said last mentioned plates'and disposed to contact with the belt.

2. In combination with an endless belt, a shaft arranged therebeneath and operated thereby, equidistantly spaced drums removably secured on the shaft, each of said drums having a plurality of radially disposed arms ends of which are bent upon themselves to provide angularly disposed fiat flanges, metallicplates secured on the said flanges, elastic scraper plates adjustably secured 0n the metallic plates, and securing elements between the elastic and the metallic plates certain of which elements connect both plates to the flanges of the arms, said elastic sell-apex. plates disposed to contact With the be t.
